Description: Certain ORION missions may require three axis stabilization. Since ORION's physical size severely limits its onboard fuel storage capability, passive stabilization techniques warrant investigation. This paper shows the development of linearized equations of motion and regions of stability with respect to gravity gradient stabilization. Gravity gradient stabilization by itself provides little yaw restoring torque; therefore, additional torque generating devices are necessary to augment the gravity gradient effect. Control moment gyros, reaction wheels, and magnetic torquers will be investigated as to their suitability for ORION.
